HARRY N. COVELL, OF NEW YORK, N. Y.

OIL-BOX.

SPECIFICATION forming part of Letters Patent No. 635,665, dated October 24, 1899.

Application filed April 1, 1899. Serial No. 711,386. (No model.)

To @ZZ whom t may concern:

Be it known that I, HARRY N. OovnLL, a citizen of the United States, and a resident of New York, (Brooklym) in the county of Kings and State of New York, have invented certain new and useful Improvements in Oil-Boxes, of which the following is a specification.

This invention consists in an improvement on the construction shown in the Beekman patent, No. 541,308, dated June 18, 1895, to which reference is herebymade for those parts of the apparatus not herein shown, the parts in the accompanying drawings being numbered to correspond with the parts shown in the drawings of said patent.

In the accompanying drawings, Figure 1 is a vertical section of an apparatus containing my improvement. Fig. 2 is a horizontal section of the same, both sections being taken through the center of the shaft.

The drum-shaft 7, pin 9, screw 11, collar 12, nut 18, bolt-receiving projections 14 and 15, disk 20, ring 2l, top opening 19, disk 22, and opening 23 may all be constructed and combined as shown in said patent to Beekman.

24 is a web cast inside of the oil-box, so as to divide the oil-box into two compartments 25 and 26, extending from below the level of the friction-pin to a point above the same. This web is preferably made of the L form shown, so as to project rst horizontally from the disk 22 and then vertically, extending completely across and adjoining the ring 2l on opposite sides of the box. It is bored so that the friction-pin passes through it, the junction between the friction-pin 9 and the screw 11 being located in the compartment 26. In the compartment 25, next to the webpartition 24, around the friction-pin is placed the felt washer 27, backed by a washer of thin sheet-iron 28, between which and the end of the shaft 7 is placed the spiral spring 29, so that the pressure of this spiral spring holds the felt washer 27 closely against the partition 24 around the friction-pin and pre vents oil from passing from the compartment 26 into the compartment 25. The compari;` ment 24 is thus made substantially oil-retain` ing, as there is no opening from it exceptingthe hole closed by the friction-pin and the threaded hole closed by the friction-screw l1 and Jthe opening at the top through which it is filled.

The fact that in my oil-box the receptacle by which the oil is held around the joint be; tween the screw and pin will not leak oil con-l stitutes it a valuable improvement over that which is shown in said Beekmanpatent.

I claim- In a rope-drum apparatus, in combination,

the drum-shaft 7, the pin 9 within said shaft, the screw 11 bearing against said pin, the nut- 13, means whereby the same is secured on op= posite sides of the end of the shaft, a box be# tween said nut and said shaft and a partition within said box whereby the oil is confined next to the end of the screw, substantially as described.
